Hi my male, neutered, 8 year old rabbit has started passing blood and clots rather than urine. We noticed a large red area in his hutch this morning so we brought him inside. he has been inside for much of the day, he has in the last hour again passed blood and clots inside. His diet has not changed recenty and he is not fed anything with significant red colour. It's the first time we have noted this blood and clots. Unfortunately we don't have any pics, it was cleaned up before thinking about it. Any help would be greatly apreciated. Thanks Dan.
